As he prepares a legislative package for President Obama's review, Vice President Biden said Friday that multiple approaches are needed to address the plague of gun violence.

"We know that there is no silver bullet ... no seat belt you can put on," Biden said before meeting with members of video game industry.

It's the latest in a string of meetings Biden has held this week, with guests ranging from gun-control advocates to gun rights supporters, hunters to retailers, mayors to governors, lawyers to doctors, and faith leaders to entertainment industry executives.

Biden has said he plans to make a series of recommendations to President Obama on Tuesday.

Obama assigned Biden the task after the Dec. 14 shooting that killed 20 students and six adults at an elementary school in Newtown, Conn. The president said he plans to make a major push for gun legislation this year; he may also issue executive orders.

The video game meeting came after the nation's biggest gun lobby, the National Rifle Association, accused the Obama administration of focusing only on gun control.

"We don't think that a ban on so-called assault weapons, which hasn't worked in the past, is going to work this time," NRA President David Keene told NBC's Today show.

Renewal of the assault weapons ban that lapsed in 2004 is an idea Obama has endorsed, along with improvements to background checks of gun purchasers and restrictions on the capacities of ammunition magazines.

Biden met with the NRA and other gun-rights groups Thursday; on Friday, he declined to respond to the group's post-meeting criticism. "I thought we had a very straightforward, productive meeting," he told reporters.

The president and vice president have said they respect the Second Amendment right of gun ownership, and are looking for common-sense ways to keep high-powered weapons away from people who shouldn't have them.

Obama and Biden have also said they want to address other factors behind gun violence, including mental health and cultural issues.

The latter concern prompted the vice president's meeting with members of the video game industry, some of whose products have been accused of desensitizing young people to the nature of violence.

"You have not been singled out," Biden said. "I come to this meeting with no judgment."
